Looks like you're right. Sorry. I must have confused you with some other commenter I read on HN today, it's a mistake on my part.
Having admitted this much, I'm still waiting for your explanation why you wouldn't "consider projects written in CoffeeScript JavaScript projects". I'd still downvote you for stating such a strong opinion without providing any rationale.
They're not JavaScript because the language used to write the source code isn't in JavaScript. Babel is used to bring modern JavaScript features into older browsers, but you're still writing JavaScript. If the language you are writing doesn't at least attempt to conform with some signficant portion of the ECMAScript specification, it's not JavaScript.
